The Reima Rapakko Rain Overall combines a fully waterproof build, with welded seams and a fabric rated for a water column over 10,000mm, with light insulation calibrated for cold rain, sleet, and slush rather than deep winter cold. That balance keeps a toddler warm without overheating while crawling, toddling, or sitting down in wet grass. The one-piece construction skips the hassle of coordinating a jacket and pants, with a front zipper that makes dressing a squirming toddler faster and simpler. What Our Gearhead(R) Experts Are Saying:"My toddler sat down in a cold, wet patch of grass mid-walk and stayed completely dry and warm underneath. One zipper and we were dressed and out the door in under a minute, which matters more with a toddler than it ever did before."
